Application October 15, 1938, Serial No. 235,271 4 Claims. (01. 225-1) The present invention relates to improvements Figure 2 a horizontal section taken along line in liquid dispensing devices and has reference IIII of Figure 1, and principally to means for dispensing liquid from Figure 3 a modified bottle holder. bottles into glasses under desired conditions. While I have shown only the preferred form 1 The invention is intended particularly for the of my invention, I wish to have it understood 5 dispensing of beer from comparatively large botthat various changes or modifications may be tles, say one-half gallon or a full gallon in size, made within the scope of the claims hereto atinto individual glasses under conditions approxitached without departing from the spirit of the mating the dispensing of beer from kegs or barinvention.

In its preferred form my invention comprises 10 Kegs or barrels can be economically used for a receptacle I, preferably rectangular in form beer dispensing in larger sizes only, and the and comprising a bottom 2, a rear wall 3, a front owner of a restaurant or tavern often finds himwall 4, side walls 5 and 6 and a top I which latter self in a position where, due to fluctuating deis formed with a suitable door 8 hinged at 9 to v mand, the beer in a keg or barrel, once opened, give access to the interior from above.

and is provided, at its outer end, with a dispensing faucet 29.

The dispensing faucet is thus presented on the opposite face of the door from that of the bottle and occupies an inverted position when the door is open, as shown in dotted lines. The conduit extends through the stopper so that the liquid may flow therethrough when'the bottle is inverted.

Flexible tubes 39 of small diameter connect the upper parts of the dry ice container with metallic tubes 3! extending centrally through the stoppers and the inner ends of the conduits into the bottles and within close proximity to the bottoms thereof.

While each bottle stopper may, of course, be individually connected to the conduit and the dry ice, I preferably arrange the stoppers in.

pairs, providing each conduit 21 -with two branches, as at 33 and each tube with similar branches indicated at 32.

The door may be held in open position during the loading operation by any suitable means as by the hook 3d.

The operation of my apparatus is as follows: For loading, the door 20 is swung into open position as shown in the .dotted lines in Figure 1.

The screw24 is loosened which causes the base25 to recede. The bottle, which has been previously installed, is then withdrawn, by a slight tilting and downward movement which causes it to clear the base and which causes the neck to move sufiiciently bendable and flexible to allow the botstopper, and means for moving the base and the this respect.

downward along the tube 3i, the latter being tle neck to clear the base.

For insertion of a fresh bottle the originalclosure ordinarily provided is first removed and the open neck of the bottle is guided over the tube 31 toward the stopper, which is preferably frustoconical in form, until it engages therewith, at which time the bottom of the bottle may be swung over the base, which latter is preferably shaped,

by flanges-35 or otherwise, to center the'bottle. Tightening of the screw now forces the base upward and tightens the engagement between the stopper and the bottle neck.

It will be noticed that this'entire operation is carried out while the bottle'occupies an upright position and withoutany danger of. spilling the contents thereof.

After all the bottles, or anyxidesiredhumber,

have thus been inserted, the door is swung downward-into the full-line'closed position of Figure 1. This operation inverts-thebottles and the contents thereof may nowbe easily'idrained by opening the faucetr29.

At the same time carbon dioxide-gas is delivered into the bottle above theliquid to keep the latter fresh and under pressure. The circulation .of the'brine or oil in the coil [7. tends ,tokeep the frontchamber cool. a A latch 35 may be used for holding the door in closed position.

The two dry ice containersare interconnected by the valvedconduitv l5 which may be shutoff when it is desired to fill one, upon opening the door 8 and removing the cap i8. v It is apparentthat my device may. beused for the dispensing of any other beverage or liquid as well. as. beer, and I do not wish to .This application embodies. certain improve-- ments over the device shown in' co-pending application, Serial No.'165,069, filed September 22,

Referring now to Figure 3, it will be noted that tending through the door and having a faucet on be limited in I have provided a bracket 23' on the inner face. of the door 20. This bracket has secured thereto a platform 25' by means of a pin and slot connection 26'. For moving the platform upon the bottle 22, I make use of an eccentric 24', 5 which has an operating handle 2'5 extending therefrom. It will be understood that the platform 25' is intended for forcing the bottle 22 I upon a stopper (not shown) in thesame manner tle presented upwardly while the door is open so 20 as to cause the door to reverse the bottle into inverted position with the discharge end of the bottle disposed downwardly when the door is closed,

a conduit extending from the discharge end of the bottle and having a faucet on the opposite' side of the door.

2. In combination, a swingable door mounted on a horizontal-axis for movement between'two substantially vertical positions, whereby the faces of the door may be transposed and inverted, a bottle supporting base and a bottle stopper mounted upon one face of the door in spaced relation to each other for receiving a bottle therebetween, a bottle disposed between said base and stopper relative to each other for urging the open end of the bottle'upon the stopper, the mounting means for the stopper including a conduit exthe opposite side of the door.
